Landfill impervious layer hole detection system and method

Abstract

The invention relates to a landfill impervious layer hole detection system and method. The detection system comprises a plurality of electrodes, a converter, a processor, and a dipolar detector. The electrodes are arranged on set positions of a waste stack. A converter is connected with the electrodes through a plurality of cables respectively to receive a plurality of potential signals sent by the electrodes and generates potential information. The processor is connected with the converter to receive and process the potential information, generates an electrical distribution graph, and determines a suspected seepage area. The dipolar detector comprises a detection cart and detection probes arranged thereon. The detection cart drives the detection probes to move in the suspected seepage area, and the detection probes determine the position of a seepage point of the suspected seepage area. The detection system and the detection method are suitable for waste stacks, can reduce labor and detection costs and the leak detection rate, largely improve the detection efficiency and precision, and provide experimental data basis for overall assessment of the completeness of an impervious layer.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a leak detection system and a detection method for an anti-seepage layer of a landfill site. Background technique [0002] The landfill is used to treat and dispose of domestic waste, with an artificial anti-seepage membrane to prevent the leakage of landfill leachate, with leachate treatment or pretreatment facilities and equipment, operation, management, maintenance and final closure are in line with sanitation Required waste disposal site. As the final disposal method of domestic waste, landfill technology is currently the main way to solve domestic waste in most cities in China. In recent years, high-density polyethylene membranes have been widely used as anti-seepage layers in landfills in China. Research findings at home and abroad and a large number of engineering practices have shown that geomembranes for anti-seepage layers are prone to damage during t...
